RADIATOR Filed June '7, 1930 4 Sheets-Sheet 4 Patented Nov; 14, 1933 RADIATOR George Wilfrid Blackmore, Pittsburgh-Pa, assignor to Automatic Gas-Steam Radiator Company, Pittsburgh, Pa., a corporation of Penn- 7 sylvania Application June 7, 1930. Serial No. 459,750 Claims. (01.126-91) My invention relates broadly to heating apparatus and more particularly to radiators of the gas-fired variety. It is herein described with reference to radiators of the gas-fired variety in 5 which an intermediateheating medium, namely,

water or steam is used.

In the art of heating by means of gas-fired devices andmore particularly gas-fired radiators, it is desirable to provide flue or chimney connections for the disposition of the products of combustion and to prevent their discharge in the roominto which the radiator is located. When such adevice is connected to a flue or chimney, means must be provided therein for the purpose of diverting any back drafts coming down the flue away from the burner and the flame thereon and outsuitable escapement openings. If such means are not provided, the flame on the burner will be extinguished by the back-draft and a dangerous condition result. The escapement openings also perform the secondary function of admitting air to the device to minimize excessive up-drafts in the flue. I

By my invention, 1 provide a radiator of the gas-fired type in which water or steam is utilized as an intermediate heating medium. The radiator which I provide is of such a construction that the back-draft gases are caused topass out of the radiator through suitable escapement openings without coming into contact at all with the burner'or the flame thereon and without causing the products of combustion to be backed up and smother out the flame. The escapement openings which I provide further serve the purpose of admitting air to relieveexcessive up-drafts.

Inthe accompanying drawings, I have shown for purposes of illustration only, a preferred embodiment of my invention.

Figure 12 is a sectional View taken between intermediate sections of a radiator embodying a modified form of my invention.

Figure'l3 is a sectional view of a radiator embodying a modified form of my inventiontaken adjacent the middle or outlet section.

Referring'to Figure 1, the radiator which I provide is comprised of a plurality of sections A, B, Ci, D and B. These sections are assembled in the relation shown in Figure 1 or may be assembled in any other preferred relationship. 1 The sections are held together by stay bolts 2 having threaded portions 3 thereon adapted to receive nuts 4. I

Each section is provided with outwardly projecting flanges 5 cooperating to receive couplings constituting fluid connections therebetween. The flanges 5 servelas'a part of, and interconnecticns between the water chambers 6. Each radiator section at its upper end is provided with horizontally extending flanges 8 cooperating for the purpose of forming fluid connections between the various sections at the upper ends thereof.

Each radiator section is further provided with a plurality of hollow tubes 9 adapted to carry the steam throughout the radiator and to transmit heat to the surrounding atmosphere.

Each section A, and E is provided with a vertically extending flange 10 on the inner face thereof. Each flange 10 extends from the bottom of the radiator up to approximately the central portion thereof. It there joins with a horizontally extending flange 11 which extends rearwardly to the rearmcst columnof the section. It there joins with a vertically extending flange 12 which extends to the bottom of the radiator. The flange 12 near the bottom of the radiator is curved inwardlyas at 13. The flanges 1G and 12 are joined at the bottom of the'radiator by a horizontally.extendingflange 14. Each of the flanges 10 and 12 have recesses 15 therein adapted to. cooperate with similar recesses in other sections. v

Each radiator section B and Cihas a yer.- ticallyextending flange 20 on each face thereof on one of the forward columns of the radiator. Each flange 20 extends from the bottom of the section upwardly to approximately the center t ereof Where it joins with a horizontally'extending flange 21 which extends to the rearmost column of the section. It there joins with a vertically extending flange 22 which is curved inwardly as at 23. The flanges and 22 are joined at the bottoms thereof by a horizontally extending flange 24. Each flange 20 and 22 has a recess 25 near the bottom thereof adapted to cooperate with similar recesses in other sections.

The radiator section D which is the middle or outlet section is provided with a vertically extending flange on each face thereof. Each flange 30 extends from the bottom of the sec tion up to approximately the center thereof, where it joins with a horizontallyextending flange 31 extending to the rearmost column of the section. A vertically extending flange 32 is provided on each face of section D on the rearmost column. This flange does not extend up to and join the horizontally extending flange 31, but is cut off, as also are the steam columns, in order to provide an outlet from the radiator. Each flange 32 is curved inwardly near the bottom thereof as at 33. The flanges 30 and 33 are joined at the bottom of the radiator by a horizontally extending flange '34. Each flange 30 and .32 has a recess 35 near the bottom thereof adapted to cooperate with similar recesses in other sections.

The system of flanges just described forms a closed chamber when the radiator sections are assembled. This closed chamber has an opening 36 in the rear thereof which constitutes a flue opening. Any suitable collar 28 can be bolted over the opening 36 in order to provide for the connection of the radiator to any desirable flue or chimney. This closed chamber also has openings 37 on each end thereof. The openings 37 are partially closed by plates 38 and 39.

Each end section is provided with a horizontally extending flange 40 on its inside face located at the top of the closure plate 38. Each section C and D is provided with horizontally extending flanges 41. These .flanges are located at approximately the same height as the flanges 40 on the end sections. The flanges 40 and 41 are complementary and adapted to flt together and form a plurality of horizontally disposed baflles and to divide the closed chamber hereinbefore described into compartments 42 and 43. The radiator sec- .tions B do not contain horizontally disposed flanges similar to those contained in the sections C and D, but are adapted to permit the products of combustion to travelfrom the compartment 42 upwardly into the compartment 43. In order to facilitate the movement of the products of combustion from the compartment 42 to the compartment 43,.several of the steam columns v9 are cut off .as best shown in Figure 4.

At the bottom of the radiator beneath the water chambers 6 any suitable burner 44 having gas connections indicated generally at 45 may be provided. The gas burner 44 extends longitudinally throughout the radiator. Combustion on the burner is aided by openings 46 which are formed by the recesses 15, 25 and 35 on the varipartment 42, through openings 48 into compartment 43, thence toward the center of the radiator and out through the opening 36 to the flue or chimney. The flanges 40 and 41 form baffles at each end of the radiator which tend to direct the products of combustion away from the atmospheric openings 3'7 and toward the flue opening 36.

When an excessive up-draft is present in the chimney or flue to which the radiator is connected, air will be drawn inwardly through the openings 37 and pass out through the flue opening 36., thereby relieving the up-draft and preventing it from pulling the flame away from the burner and extinguishing it.

When a down-draft is present in the flue to which the radiator is connected, the down-draft enters the radiator through the flue opening 36 and is directed toward the atmospheric openings 3'? by the front wall and the baffle formed under the flue opening by means of flanges 41 on section D and the adjoining sections C. This baffle prevents the back-draft from passing down through the compartment 42 onto the burner.

When a down-draft is present, the products of combustion rise around the water chambers '6 as they do under normal conditions, pass upwardly through compartment 42 through openings 48,

and are discharged into the surrounding atmosphere through the openings '37, together with the back-draft gases. Thus it may be seen that the operation of the radiator is not detrimentally affected by back-drafts or excessive up-d-rafts.

In the modified form of my invention shown in Figures 12 and 13, each end section has formed on its inner face and each intermediate section on both faces, a vertically extending flange 50. Each vertically extending flange 50 is joined near the middle of the section with a horizontally ex tending flange 51 which extends to the rearmost column of the section. Each flange 51 joins a vertically extending flange 52 on the rearmost column of the radiator. Each flange 52 extends to the bottom of the radiator section and is curved inwardly as at 53 and downwardly as at '54 3 near the bottom thereof. Each flange 59 and 52 is joined at the bottom of the radiator by a horizontally extending flange 55. Each flange 50 and 52 has a recess 56 therein for the purpose of forming secondary air openings similar to the openings 46 described in connection with my preferred embodiment.

As best shown in Figure 13, the middle or out let section of my modified form of radiator has formed thereon on each face thereof a vertically extending flange 60. Each vertically extending flange 60 adjoins a horizontally extending flange 61 near the center of the section. Each horizontally extending flange 61 is curved downwardly as at 62. On each face of the outlet section on the .rearmost column is provided a vertically extending flange 63. The flange 63 does not extend upwardly to and join the flange 62, but is cut oif in order to provide an opening to the flue. Each flange 63 is curved inwardly near the bottom thereof as at 64 and downwardly as at 65. The flanges 60 and 63 are joined near the bottom of the radiator by a flange 66. Recesses'67 are provided in the flanges 60 and 63 for the purpose of forming secondary air openings as hereinbefore described.

The flanges are adapted to fit together and form a closed chamber similar to the closed chamber described with reference to my preferred form. The closed chamber formed by the flanges has L atmospheric openings at each end'a'nd a flue opening [71 in the central section. The openings '70 are partially closed by closure plates '72and '13 at each end of the radiator. Each section of my modified form of radiator has horizontally disposed flanges 74 and 75 thereon in spaced relationship These flanges 74 and '75 oneach section are complementary and are adapted to form horizontal baffies extending throughout the length of the radiator. The baffle formed by the flanges 74 is adapted to extend forwardly from the rear wall of the closed chamber to a point spaced from the front wall. The baffle formed by the flanges 75 extends rearwardly from the front wall of the closed chamber, terminating at a point spaced from the rear wall.

In operation, the products of combustion pass upwardly from the burner 77 around the water chamber 76 and impinge on the baille formed by the flanges '74. The products of combustion are directed forwardly and pass upwardly through opening 78, and are directed to the rear of the radiator by the bafiie formed by flanges '75 and pass upwardly through opening 79 into the cham- I ber 80. Under normal conditions of operation, the products of combustion then pass outwardly through the flue opening 71, to which a collar 81 is attached, in order to enable the opening to be connected to a suitable flue or chimney.

Under down-draft conditions, that is, when a draft is coming down the chimney or flue to which the radiator is connected, the down-draft enters the radiator through flue opening 71 and is prevented from passing downwardly to the burner by the bafiles formed by the flanges 74 and 75. The down-draft gases are caused to pass sidewise through the radiator and out through openings '70 into the surrounding atmosphere. Under downdraft conditions, the products of combustion rise upwardly through the radiator as heretofore described, and are carried out through openings 70 by the down-draft.

When an excessive up-draft is present in the flue, air is drawn in through openings 70 on each end of the radiator to satisfy it. Consequently,

the flame on the burner is not affected by the.

up-draft.
